To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that
$4x + 20 = 3x + 55$
we can subtract twenty from each side
$4x + (20 - 20) = 3x + (55 - 20)$
$4x = 3x + 35$
now we can subtract like terms
$4x - 3x = (3x - 3x) + 35$
so we can get the final answer as
$1x = 35$

How to factor the algebraic expression 24a + 28

bonufazy [111]

So use undistributive properyt]
ab+ac=a(b+c)
so factor 24a dadn 28 to find 'a' the common factor
24=2 times 2 times 2 times 3 tiems a
28=2 times 2 times 7
common one is 2 itmes 2=4
a=4
4(2 times3 times a)+4(7)=4(6a)+4(7)=4(6a+7)
